CONSCAN:

The Final Touch.

High-torque motors positionthe antenna and keep theantenna firmly locked-in onthe selected satellite.

As satellite frequencies climb into the Ka-band range, antenna misalignment tolerances become vanishingly small. We have chosen to leave nothing to chance. All antenna systems incorporate an aggressive, proactive signal tracking system called conical scanning CONSCAN. This system reads the signal strength in each quadrant of the antenna and feeds this information to the system’s Digital Antenna Control Unit which then micro-steps the antenna alignment to ensure equal signal strength in all four antenna quadrants. The signal is sampled at 1,000 times per second with the tracking sensitivity adjustable to the frequency and the antenna size.

Conical signal-strength scan

Sea Tel's patented, 3-axis stabilization system isolates theantenna from the ship’s motion no matter how rough the weather and seas. The antenna system responds to ship’s movement at a rate as fast as 90 degrees per second. The result? A maximum 0.2°error in the presence of +25°roll or +15°pitch ship motion and the ability to acquire the full range of frequencies from L-band to Ka-band. At last high- frequency, high-speed satellite data transmissions can be reliably received at sea!
